It's everything you'd get from a class, but way cheaper and more personalized! Summary: Non-traditional MCAT student takes the MCAT, after taking all of his pre-reqs in one year. He thought C/P was hard but you need to trust in your knowledge. CARS was easy for him. B/B was random. Khan Academy saved P/S for him.

The formula for the m.o.i. of a pulley is 1/2mr^2, where m is the mass and r is the radius. So the m.o.i. of your pulley would be I=1/2*5kg*.25m^2=.156kg*m^2. The product of the m.o.i. and the angular velocity is going to equal the torque (rotational force) on the pulley. The tension in the rope, in turn, is equal to the torque on the pulley ...Resonance is exemplified by a large amount of energy transfer to the object and a dramatic increase in amplitude. To investigate resonance, an experiment is performed wherein a speaker plays sound towards a tube of length D=2.0 meters which is open at both ends. The frequency of the speaker can be adjusted. The refractive index tells you the speed of light in a given material. it is defined as n = c/v. where c is speed of light in vaccum, and v is velocity of light in the material. The refractive index is used in (not defined by) Snell's law, which relates the angle of incidence to the angle of refraction when light passes from one material into ...Preliminary investigations involved three volunteer patients wheeling their way up the ramp individually and providing feedback on the difficulty of the exercise.

Wow, thats fantastic!!! I did TPR only the first time around and so much god damn details. But, I heard KA was the way to go bc its less detail and to the point but i just got a little scared bc ...

Capacitors use non-conducting materials, or dielectrics, to store charge and increase capacitance. Dielectrics, when placed between charged capacitor plates, become polarized, reducing the voltage across the plates and increasing capacitance. The degree of capacitance increase depends on the dielectric constant of the material used.

It is possible to determine the probability that a single atomic nucleus will "survive" during a given interval. This probability amounts to 50% for one half-life. In an interval twice as long (2 T) the nucleus survives only with a 25% probability (half of 50%), in an interval of three half-life periods (3 T) only with 12.5% (half of 25%), and ...

FTB. 11 years ago. Yes, there are three types of nuclear decay. Alpha decay - an alpha particle emitted (alpha particle = nucleus of He atom --> 2 protons and 2 neutrons) Beta decay - an electron or positron and a type of neutrino emitted. Gamma decay - a gamma wave emitted.Atomic nucleus questions. Which of the following isotopes is the most likely X in the reaction 92 236 U → 36 92 K r + 3 n + X , where n denotes a free neutron?

So let's go ahead and do that. We're gonna multiply all those things together. So we take the mass of an electron, 9.11 times 10 to the negative 31st.In non-humid air at 20 degrees Celsius, the speed of sound is about 343 meters per second or 767 miles per hour. We can also watch the speed of sound of a repeating simple harmonic wave. The speed of the wave can again be determined by the speed of the compressed regions as they travel through the medium.Learn for free about math, art, computer programming, economics, physics, chemistry, biology, medicine, finance, history, and more.

Video transcript. - Check out this speaker. If we plug it in, it makes sound. (speaker hums) The way this speaker creates sound is by moving the front of the speaker, which is called the diaphragm, back and forth rapidly. Scientists often use the word oscillation to refer to the back and forth motion of an object.

The work done by the gas is equal to negative the work done on the gas because if the gas does 100 Joules of work that's, like, someone doing negative 100 Joules of work on the gas. Because if you do negative work on an object you're actually taking energy away from it. So, that's the first law of thermodynamics.Resonance is exemplified by a large amount of energy transfer to the object and a dramatic increase in amplitude. To investigate resonance, an experiment is performed wherein a speaker plays sound towards a tube of length D=2.0 meters which is open at both ends. The frequency of the speaker can be adjusted.

The student pulls the mass a distance x ‍ from equilibrium and releases it from rest. The student then measures the maximum speed of the mass during its oscillation and calculates the total mechanical energy, E total ‍ , of the system.
